The smallest unit to measure length is?
The smallest unit is the Planck Length. Theoretically, it is not that there can be nothing smaller, but for various reasons that have nothing to do with the limits of technology there is nothing that can be known about anything that happens to be smaller. For scale, the number of Planck Lengths in the diameter of a proton is 10 to the twentieth power.
How fast is Planck time?
Planck length and Planck time Planck time is the time it would take a photon moving at the speed of light in a vacuum to cross a distance equal to the Planck length. The Planck length is 1.616252 × 10−35 meters, and the Planck time is 5.39121 × 10−44 seconds. Links are provided to the relevant Wikipedia articles.
How many electrons would fit in the universe?
somewhere around 4*10^184 planck cubes could fit in the obervable universe and those are a lot smaller than electrons. So that number would be somewhere between a googol and this number.
How many planck lengths are in a yottameter?
1059 (1E+59), there are 100,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 Planck Lengths in a Yottameter.
What is planck constant?
Planck's constant describes the ratio between the energy of an electromagnetic wave and the frequency of that wave.
What is a smaller unit than a plank?
The "Planck units" are generally the smallest units used - except for the Planck unit for mass, which is fairly large.
Are neutrinos smaller than a Planck Unit?
Yes, neutrinos are subatomic particles with a very small, non-zero mass. They are much larger than the Planck length, which is the scale at which quantum effects of gravity become important.
Is anything smaller than a planck length?
Currently, the Planck length is believed to be the smallest meaningful unit of length in physics. It is thought to represent the scale at which classical notions of spacetime cease to be valid, and quantum effects dominate. However, due to the limitations of our current understanding of physics at such small scales, it is uncertain if anything smaller than the Planck length exists.
Which is smaller Planck time or yoctosecond?
Planck Time Because 5.4*10^-44 seconds
How big is a plank length?
Planck lenght is equal to 1.616252×10−35 meters. 1020 times smaller than the diameter of a proton.
What is planck lenghth?
It is the smallest length scientists have discovered. Anything smaller makes "no physical sense"

What is smaller than picosecond?
a femto second is 1000 times smaller 10-15 an atto second is 1000000 times smaller 10-18 According to current thinking, one Planck time = 5.39 * 10-44 seconds is the smallest unit of time that it will ever be possible to measure.
What was Planck's name?
Max Planck.
What is energy of electromagnetic?
It's what we call a "photon". Its energy is the product of its frequency and Planck's Konstant. No smaller bundle of energy can exist at that frequency.
What is the planck distance?
The Planck distance, or Planck length, is 1.6 x 10^-35 meters.
What is the shortest thing on earth?
An atom. __________ Not an atom; not by a long shot. If units of length count, then the winner would be the Planck Length, defined at 1.616252 X (10 to the power -35) meters, smaller than any known elementary particle.
